Before I try to even find a replacement motor for my JM glove, does anyone know if something can be done to stop a terrible squealing noise that the motor makes when the glove travels forward and backward? Sounds like its coming from the gear box attached to the motor. I don't think that is serviceable without splitting it open (and then what?) It doesn't sound like the X or Y nut (not sure which is which), but maybe that's contributing to the noise if its making the rod hard to turn. Any thoughts? Any leads on a new or used hand motor? Thanks!
